T G FF ICE MOP W'RINGER.

Application filed May 16,

To all whom it may concern: w

Be it known that I, PETER C. COURTE- MANGHE, a citizen of the United States, and aresident of Claremont, in the county of Sullivan and State of New Hampshire, have invented a new and Improved Mop lVringer, of which the following is a full, clear, and exact description. I i

The invention relates to that class of mop wringers in which the water is squeezed out of the mop by presser plates, and the object of the invention is to provide a wringer of the character indicated, which is very effective in operation, easily operated, simple and :1 cheap. 7

The invention consists of the construction and arrangement of parts hereinafter described and pointed out in the claims.

In the accompanying drawing forming. a part of this specification similar reference characters indicate corresponding parts in all the views.

In said drawing,

Fig. 1 is a top plan view of an embodiment at present preferred;

Fig. 2 is a vertical longitudinal sectional view, taken on line 22 of Fig. 1; and

Fig. 3 is a transverse sectional view taken on the line 33 of Fig. 2.

In the present case the receptacle, indicated at 4, is of sheet metal and of rectangular horizontal section, and carries permanently, as by means of rivets 5 on each side, an interior substantially triangular plate 6.

Plates 6 are formed as angularly bent terminal portions of a unitary sheet metal structure the intermediate portion of which constitutes a vertically fixed squeezer plate 7 subtended by an inclined shelf portion 8.

The upper marginal portion of squeezer member 7 is also bent away from the main plan-e of the member, as indicated at 9; and this part of member 7, which may be called the ledge 9, supports by gravity the handle 10 of a bail 11 when receptacle 4 has been transported to a desired location.

The free ends of this bail are bent to take loosely about a transverse rock shaft 12; the opposite ends of shaft 12 being given a journalling support as the result of resting on the outwardly flanged open top of receptacle 4, and as the result of being loosely caught under hook-shaped formations provided at the upper vertical corners of plates 6 as indicated in broken lines at 14 in Fig. 2.

Inside receptacle 4 this rock shaft 12 has,

1923. Serial No. 639,431.

pinned or otherwise fixedly mounted thereon, a pair of downwardly extending arms 15,

the swinging ends of which are connected by links 16 to the swinging squeezer plate 17. Plate 17, at opposite sides has depending arm-like extensions 18 whereby plate 17 at opposite sides and near the bottom of the receptacle, may be pivotally mounted on plates 6 as indicated at 19.

A s-inglethrust pedal operated means for swinging squeezer member 17 in a clockwise direction into a substantially vertical disposition relative to fixed squeezer member 7, comprises the following parts, all exterior to receptacle 4: A treadle board 20 spans the swinging ends of a pair of long levers 21 pivoted at their opposite ends to the side walls of receptacle 4 belowthe points of pivoting of movable squeezer member 17 as at 22 and each of these levers 21 is normally upheld as shown by a retractile coil spring 23 and is operatively connected to rock shaft 12 by means of links 24 and short arms 25 pinned or otherwise suitably fixed on said shaft.

Movable squeezer member 17 is provided with a multiplicity of small transverse openings as clearly shown in all the views, and fixed squeezer member 7 is: similarly foraminous, as indicated in Fig. 2.

It is pointed out that while rock shaft 12 is located slightly off the longitudinal center of receptacle 4, nevertheless on lifting handle 10 and hail 11, the weight distribution will be such that during transport of the complete apparatus the bottom of the receptacle will be suspended substantially hori zontal. It will further be noted that, as the result of such provision, and incident to the elongation of receptacle 4 in the direction of extension of pedal-actuator 2021, the latter operates on a comparatively long leverage, and, further, the receptacle 4 includes a readily accessible portion 4 into which a small bucket or pail may be dipped to remove dirty water when the receptacle 4 approaches overflow as the result of having been repeatedly used for mop-wringing purposes when in one particular location on a floor.

During mop-wringing, it will be understood that the mop-wielder, holding the mop-handle and standing upright, has merely to lower the mop between the squeezer members 7 and 17 as normally relatively disposed as shown in the drawing, and then,

when the lower free end of the mop reaches to or almost to shelf 8, foot-pressure is applied to treadle 20 to swing, through the parts described, squeezer member 17 flat against the mop and towring the latter completely by forcing the carried water to be squirted through the multiplicity of transverse openings in the two squeezer members. Release of foot-pressure on treadle 2O permits spring 23 instantaneously to return the parts to the positions shown in Fig. 2, whereupon the wrung mop is freed to be swung clear of the wringer.

I claim:

1. In a mop wringer, a receptacle, a fixed presser plate in the receptacle, a pivoted pressure plate, a transverse rock shaft mounted on the receptacle and provided outside and within the receptacle with arms, links connecting the arms of the shaft in the receptacle with the pivoted presser plate, treadle levers pivoted at their ends to the receptacle, and links connecting the treadle levers with the arms of the shaft outside of the receptacle.

2. In a mop wringer, a receptacle, a frame secured in the receptacle, the front member of which forms a fixed presser plate, a movable presser plate pivoted to the lower front portion of the frame, a rock shaft mounted on the receptacle, means for operating said ,side members of which are provided with notches, a pivoted presser plate, a rock shaft resting on the upper edge of the receptacle and engaged by the notches of the frame, and means for operating the pivoted presser plate from the rock shaft.

4. In a mop wringer, a receptacle, a frame comprising side plates and a front end plate forming a fixed presser plate and having an outwardly extending flange at its upper end,

the side plates being provided with notches, a pivoted presser plate, a rock shaft resting on the upper edge of the receptacle and engaged by the notches of the side plates of the frame, means for operating the pivoted 1;

presser plate from the rock'shaft, and a bail having its ends loosely bent around the rock shaft, the handle of the bail normally resting on the flanges of the fixed presser plate.
